Saipem SPA, an Italian energy engineering and construction firm, has achieved a significant milestone in hydrogen pipeline technology by securing Approval in Principle (AiP) and Technology Qualification certifications from classification society RINA. These certifications validate Saipem's methodology for qualifying materials used in subsea hydrogen pipelines, a critical component in the energy transition.

Transporting hydrogen through pipelines presents unique challenges, particularly the risk of material degradation. Saipem has developed a comprehensive protocol to assess the performance of metals and welds exposed to hydrogen, ensuring the integrity and compatibility of the pipelines during construction and operation.

These newly obtained certifications from RINA enable the broader application of Saipem's protocol, paving the way for large-scale deployment of subsea hydrogen pipelines. This technology is poised to become a vital solution for the transportation of gaseous hydrogen, contributing to global energy transition efforts.

Saipem had earlier announced a significant industrial breakthrough by adapting a pipeline lining technology--initially developed by United Pipeline Systems for onshore use--to offshore and subsea environments. This innovation, which replaces corrosion-resistant alloys with plastic coatings inside the pipelines, has earned a Statement of Qualified Technology from DNV. The certification confirms the technology's suitability for even the most challenging conditions, including ultra-deepwater and high-pressure pipelines.

Saipem anticipates that the new technology will reduce overall system costs by up to 40 percent. Initially, the company will focus on water injection pipelines, with plans to expand to risers. The technology targets traditional offshore markets like the Middle East and new frontiers such as the Gulf of Mexico and Brazil.
